A FOR/V578 BILL TAIBKINS, OF MOORINGSPORT, LOUISIANA.

NUT-LOCK.

Application filed September 22, 1914.

To all whom it may concern:

Be it known that I, BILL TABKINS, of Mooringsport, Caddo parish, Stateof Louisiana, have invented a new and Improved Nut-Lock, of which thefollowing is a full, clear, and exact description.

My invention relates particularly to a device to lock a nut on alongitudinally grooved bolt.

The prime object of the invention is to provide a device for theindicated purpose, of simple, strong and cheap construction, which canbe readily applied in a way to hold the nut securely against turning onthe bolt, while adaptedto be removed with facility when desired.

The invention will be particularly eX- plained in the specificdescription following.

Figure 1 is a front view of my improved nut lock, showing the sameapplied. Fig. 2 is a side elevation of the device applied. Fig. 3 is aplan view of the device applied, and Fig. lis a separate perspectiveview of the nut lock.

My improved device is formed to secure the nut B of usual form on a boltA. It is to be understood that the bolt and nut may be employed to clampany two or more members G together, said members being conventionallyillustrated.

My improved nut lock comprises two end members 10 spaced apart toreceive a nut between them, and embrace the same at opposite sides. Themembers are joined by longitudinal bars 11 parallel, or approximatelyso, with each other. The bars 11 are integral with the end members 10,and join one end of one member with the corresponding end of the othermember. The longitudinal bars 11 are spaced apart a distance slightlyless than sufficient to receive between them transversely the bolt A. Itwill be noted that the end members have a drop between their ends, andpreferably they are in bowed form. On the inner face of each bar 11 Iprovide a tooth 12, the said teeth preferably being directly oppositeeach other. Desirably, the teeth 12 are of the general form of ratchetteeth, thereby presenting each a front surface perpendicular to theinner face of the adjacent lon- Specification of Letters Patent.

gitudinal bar 11, and an inclined back surace.

In practice, after the nut B has been screwed up tightly, the nut lockis so positioned that the end members 10 will lie at opposite sides ofthe nut, and the bars 11 adjacent to the outer end of the bolt. Theteeth 12 will thus overlap the front end of the bolt, and a blow from ahammer or like tool delivered against the bars 11, will cause the teeth12 to out grooves a longitudinally of the bolt.

The end members 10 are more or less resilient, and if it is desired toremove the nut look, a tool D of the general character of nippers isemployed. The nose of the tool is entered between the bars 11, and thelatter separated to relieve the gripping action of the teeth 12 in thegrooves c.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is:

1. A nut lock to engage a bolt and a nut thereon, said lock comprisingbowed resilient end members, approximately parallel spaced bars integralwith said end members, each connecting one end of one member with thecorresponding end of the other member, said bowed end members presentinga drop between the ends thereof, and a tooth on the inner face of eachbar, the teeth being disposed oppositely to each other and eachpresenting an inclined face, and a face approximately at right angles tothe inner face of the adjacent bar.

2. A nut lock of the character described comprising longitudinal barsspaced to receive a bolt, transverse end members uniting adjacent endsof the respective bars, the said end members having each a drop betweenthe bars and adapted to embrace opposite sides of a nut, and a lateraltooth on the inner face of one of the bars, the tooth projecting towardthe opposite bar.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

BILL TABKINS.
